Abstract
This letter presents a quantitative approach to the investigation
of subject-specific on-body communication channels.
To this aim, propagation at 5.8 GHz has been studied considering
50 realistic digital phantoms, statistically generated from a set of 20
magnetic resonance (MR) scans. Both line-of-sight (LoS) and nonline-of-sight
(NLoS) communication links have been taken into account.
Mathematical expressions are proposed reflecting the correlation
between body dimensions (specifically height and waist) and
path-loss variation. Results show that linear fitting can be extrapolated
between path-loss variations and body shape parameters.
In-house parallel finite-difference time-domain (PFDTD) numerical
method has been applied to carry out full-wave simulations on
the 50 digital phantoms.
